Urgent! not getting emails

I installed clamav from Art's and all went well. Then, when I installed qmail-scanner I get this message and I can send emails now but cannot receive any and there is no mail in the webmail when testing.

[root@godslove root]# /usr/bin/qmail-scanner-reconfigure Configuring qmail-scanner: install: cannot stat `qmail-scanner-queue.pl': No such file or directory setuidgid: fatal: unable to run /var/qmail/bin/qmail-scanner-queue.pl: file does not exist setuidgid: fatal: unable to run /var/qmail/bin/qmail-scanner-queue.pl: file does not exist chmod: failed to get attributes of `/var/qmail/bin/qmail-scanner-queue.pl': No such file or directory OK
